Area(s) with issue?

ZoomIt

Steps to reproduce

1. Enable ZoomIt
2. Zoom in (Ctrl+1)
3. Optionally zoom in further (Ctrl+scroll up) to make the issue more apparent
4. Click to lock the screen and enter draw mode
5. Move the mouse and observe the cursor movement

✔️ Expected Behavior

Mouse sensitivity should remain consistent relative to the physical screen size, regardless of zoom level.

Example:
If moving the mouse by 1 cm causes the cursor to move ~2 cm on the screen when not zoomed, then the same 1 cm physical movement should result in a ~2 cm visible movement on the zoomed view as well.
In other words, ZoomIt should scale cursor movement so that the perceived distance on the screen (not raw pixels) remains the same before and after zooming.

❌ Actual Behavior

When zoomed in, the cursor appears to move the same number of pixels as when not zoomed.

This causes the cursor to cover a much larger visible distance on the zoomed-in image, making mouse movement feel excessively fast and imprecise at higher zoom levels.
